To all whom it concern:

Be it known t at I, ERNEST OANrnLo WHITE, a citizen of the UnitedStates, residing in the borough of the Bronx of the city of New York, inthe State of New York, have invented certain new and useful Improvementsin Shade-Holders, of which the .brass shell sockets, the lower endhaving a small bead, and porcelain shell sockets having a groove nearthe lower end. There are now used several forms of shade holders madefor attachment to the brass shell sockets, but such holders cannot beattached to porcelain sockets and, conversely, the types of holderswhich are applicable to porcelain sockets cannot be adapted to brasssockets, or if so attached support the shade or reflector out of properalinement with the light source or eccentrically thereto. Further, suchknown holders are most diflicult of manipulation in attaching to theshell socket and in attaching the shade or reflector thereto and oftencause injury or permanent distortion of the shell.

The improved holder, when attached to a shell socket, provides a firmgrip with a maximum and uniform surface contact thereby eliminating suchstresses on the shell as would tend to distort orbreak the same. ltalsoprovides a universality of application to shell sockets of all knowntypes and insures a ready and concentric adjust- It further provides ashade holder which is of simple construction and neat in appearance.

Another object of the invention is to provide an improved adjustablesupport for reflectors, such as are particularly adapted for showwindows and the like and in which it is desired to change the angularrelation the reflector to the axis of the light.

In accordance with the first named object of the invention, there isprovided a relatively flexible shell towhich the shade or reflector maybe readily attached and within which is carried a flexible ring adaptedto be held in a horizontal ipeeiflcation rt Letters Patent. ;Pa,te t d1,1 6,124 1 Application filed January 14, 1920.

and to permit the angularity of the reflector with respect to the axisof the lamp to be varied for windows of different heights, depths orother proportions.

he invention will be described with greater particularity hereinafterwith reference to the accompanying drawings, in which a Figure 1 is afragmentary view in section through a shade and the improved shadeholder and showing particularly the relation thereof to the shell socketand bulb.

ig. 8 is a detail view showing the relation of the adjusting screw tothe adjustable arm of 'Fig. 5.

10-10 and looking in the direction of the arrows.

While it will be appreciated as the description proceeds that one of themost important features of the invention resides in the universality ofadjustment of the improved shade holders to sockets of varying types anddimensions, there is illustrated in ig. 1, by way of example, aporcelain shell socket it having adjacent its lower end an.

The shade holder comprises generally a relatively inflexible shell b, ofannular form carrying thumb screws 0 at suitable points for engagementwith the usual heel or lip 03 at the upper edge of the shade d. Theengagement anddisengagement of the shade a1 with the shell I) throughaxis being preferably limited in their distortion by relativelyinflexible concentric shoes f secured to the inner face of the ring. Thesurface contact afforded between the ring f and the shell socket is ofvery substantial area so that a very secure gripping is effected. Thisunirorm and firm surface I contact is of such substantial area as toprevent the imposition of undue stresses on the shell socket a such aswould tend to distort or break the same. The weight of the shade d isborne at such engaging surfaces and the security of the whole enhancedto a degree by the engagement of the shell and the enlar ement a withthe lower edge of the light where it will be-most useful. Devices thethumb screws 0 will be effected m the manner commonly employed. Passingloosely through holes 6" at another section of the shell b are twodiametrically alined screws 6 having enlarged heads 6 adapted to bear inthe extreme inner position of the screws against the surface of theshell. These screws are in threaded engagement with a flexible ring f,and one suitable method of eflecting the engagement between the'ring andthe screw is illustrated in detail in Fig. 4. As there shown the ring fcarries therein a threaded bushing 9 through which the screw e passesand the inner end of the screwmay be ofi'set, as at 6 to prevent itscomplete withdrawal from the bushing. The ring 7 is of such diameter asto clear freely the enlarged lower end a of the shell socket on whichwould correspond, in the case of a metal socket, to the usual bead orexternal thread thereon.

The method of applying the shade holder readily to a shell socket, suchas a, will be apparent. Whether or not the shade d is first attached tothe shell I) of the holder, the screws e are threaded inwardly until thering f assumes approximately its normal circular set. The holder is thenpassed over the shell socket a until the ring f is in alinement with thegroove a, or in the case of a metal socket, is above such bead as willcor-- respond to the annular enlargement a on the shell. By setting upon the screws 6 the flexible ring f is distorted and assumes thegenerally elliptical form illustrated in Fig. 2, the sides thereof alongthe minor axis being drawn into firm engagement with the surface of theshell socket at the bottom of the groove a, and the sides along themajor are rovided for locking the ring ad'ustably in xed relation 'tothe shell 6. uitable means for this purpose may comprise one or morestuds f secured to the ring f along an axis substantially at rightangles to the axis of the screws 6 which stud or studs by manualdistortion of the ring may be passed through any one of several holes fin the shell, during assembling, to give the desired angular relation btween the reflector d carried with the shell and the vertical axis ofthe lamp.

As illustrated in Fig. 3, the relatively inflexible shell of theimproved holder might be readily constructed so as to accommodate shadesof much larger diameter. In this case there is provided a shoulderedflange B of much greater diameter than the body portion B and thisshouldered flange B will carry therein a plurality of thumb screws forengagement with the larger shade. In this manner, the standardization ofthe holder for application to shell sockets of usual dimensions may beaccomplished while provision is made for attachment of shades orreflectors of varying sizes.

Another embodiment of the invention is illustrated in Fig. 5 in itsassociation with a form of the improved shade holder showing a specialadaptation for supporting a glass show window reflector made without theusual heel or li for engagement with the shade holder. l roadlyconsidered, this support comprises a plurality of depending arms adaptedto be inserted through the upper opening in the reflector, at least oneof which is adjustable for the purpose of facilitating the engagementand dlsengagement of the arms with the reflector and the adjustment ofthe angularity of the reflector so heel or lip for engagement withsupporting devices. The shade holder z' which may be of the formpreviously described has secured to its inner surface two dependin armsis which are relatively rigid and whic are flanged at their lower en s,as at k, to en age the inner face of the reflector at olnts adjacent itsupper edge It. .In the illustrated embodiment, the third su porting armZ is adjustably carried by the older 13 through the medium of a screw mwhich passes loosely through an opening in the wall of the holder 1; andmay be threaded in a bushing m secured in the arm Z in much the manner.described inconnection with the construction shown in Fig. 4. The head mof the screw m is exposed to facilitate adjustment of the arm Z in amanner to be described. The inner end of the screw 'm may be upset, asindicated at m, to prevent its com lete retraction from the bushing m.The upper end of the arm Z may be confined by extending loosely througha slot 5 formed in the upper wall of the holder 2', the efl'ect beingsomewhat that of a hinged joint whereby free movement of I the lower endof the arm Z is permitted. At

the lower end of the arm Z may be stamped out three spaced lugsZ', Z Zon an one of which the upper edge k of the re ector may rest. For theconvenience of the window trimmer each of these lugs may be stamped witha suitable legend indicating the pro er lug for the support of thereflector spending upon the proportions of the window to be lighted. is

In the use of the improved support the screw we may be backed out topermit movement of the arm Z to such a position as will enable thetrimmer to pass the three arms is, Z through the upper opening in thereflector h. The flanges k of the relatively rigid arms is will then beengaged with the inner wall of the reflector h and the proper one of thethree lugs Z, Z Z will be drawn into engagement with the reflector bysetting up on the screw m. When the window is relatively deep it willobviously be desirable to throw the light rearwardly to a greater extentthan if the window be shallow and to attain this end the reflector Itwill be inclined at a substantial angle with respect to the axis of thelight source a. In this case, the rearmost portion of the reflector Itwill be tilted upwardl gaging the uppermost lug Z on t e arm Z with thereflector. For windows of medium depth it will be desirable to decreasethe by enangular relation between the reflector and the light source a,and in such case the second lug Z will be used for the support of therearmost portion of the reflector, as indicated in F1 5. For shallowwindows where the lig t is to be focused more di rectly downwardly thelowermost lug Z is used as the support. By providing an adustable arm,such as Z, and properly graduatmg the lugs Z, Z, Z for windowsof dif--ferent dimensions, the personal factor is discounted and the trimmerwill select the appropriate lug accordingto the directions. I A furtherfeature of the invention which is important in fixtures used for windowlighting where the space is cramped resides in the accessibility 0 allof the parts which must be manipulated. The thumb screws 0 which areemployed for drawing the flexible band 0' into firm surface contact withthe shell socket p will be placed on an axis extending substantially atright angles to the axis 0 the screw on and in a plane parallel to thewindow ane so that the holder may be readily attac ed to the shellsocket. The screw m will be placed in the holder 11 at the side remotefrom the window pane so as to be readily accessible to the windowtrimmer. These advantages result from the peculiar character of theimproved devices and become of considerable practical importance in theart. In this form of shade holder a stud o isshown on the ring 0 forengagement with the shell i, it being .contemplated that the shell shallbe fixed in a horizontal position while the reflector shall be adjustedangularly in the manner de scribed.

The holder shown in Figs. 9 and 10 may be substantially like that shownin Fig. 1 105 including a relatively inflexible shell 12, a flexibleband 12 carried therein and adapted to be drawn into en agement with theshell socket by means 0 diametrically opposed screws said flexible ringcarrying dia- 110 metrica ly opposed studs p which may be engaged withany one of a series of holes 12' formed in the shell at opposite sidesthereof and in the same vertical plane with the studs 79 ;When the studs12 rest in one set of 115 holes 12, as shown in Fig. 9, the shell willbe held in a horizontal position. If the studs 17 are retracted fromthat set of holes and the shell 79 tilted about the screws in onedirection or the other, the studs will 120 be engaged with another setof holes for the purpose of fixing the shell in such angular position.Hinged to the shell p are a series of pendant arms 9 which may,conveniently, be four in number and arranged mounted on the arms 9 is aclamping'ring 8 provided with holes. 8' therein throu h which the armsextend loosely, respective y, and preferably formed with a flan e s tooverliethe outer surface of the reflector 1* when the clamping ring isin position. The ring 8 has a central opening 8 therein to receive thelamp t. 1

The adjustment of the angular relation of the reflector r with relationto the axis of the lamp t is secured in this embodiment? in somewhatdifferent manner than in the embodiment shown in Fig. 1 in which thereflector d is fixedly secured to the shell. In adjusting the angularrelation of the reflector d shown in Fig. 1 with relation to the axisofthe lamp the reflector will swing about the screws e as a center. Inadjusting the angularity ofthe reflector 1' shown in Fig. 9 thereflector will swing about its own center of gravity in assumin anangular position with relation to the axis of the lamp. In effecting theadjustment, assuming that the arms 9' are disengaged from the reflectorr the shell p will be locked in the horizontal or in the desired angularposition to give the resulting inclination of the reflector-1' for themost useful reflectionof light depending upon the character of thewindow. For instance, when the shell p is in a horizontal position, asshown in Fig. 9, the ring 8 may be slid upwardly along the arms 9 tomove the lower ends of these arms inwardly, the

diametrical distance between the holes 8' in the ring being less thanthe diameter of the shell 12, whereby the arms 9 are inclined downwardlyand inwardly at all times. The result is that when thering s is movedupwardly along said arms the latter have their lower ends moved towardone another. The reflector 9 will then be moved into position to receivethe ends of the arms through its upper opening and the clamping ring 8then moved downwardly to throw the lower end of said arms outwardly andinto engagement with the inner surface of the reflector as shown in Fig.9. The final movement of the clamping ring 8 to bring the flange 8 intoengagement with the outer surface of the reflector r serves to clamp allof the arms 9' in fixed engagement with the reflector 7- so that thelatteris securely held in place. The illustrated embodiment has shown areflector of such form that when the shell 2 is fixed in horizontalposition the reflector will throw the light somewhat rearwardly of thevertical axis of the lamp as would be desirable in display windows ofmedium depth. In this case, one of the pendant arms V6 may be shorterthan its op posite arm. hen the shell 30 is tilted up and the studsenter into holes in the shell along the line indicated at tt, the arm 2will be lowered while its opposite arm Wlll be raised and the reflector1' will swing about at ed that changes in directly downwardly, as wouldbe esirable in a shallow window. When the shell p is tilted in. theopposite direction about the screws p through the studs p alon the lineindicated at uu, the arm will e raised to the position indicated indotted lines and its opposite arm will be lowered correspondingly andthe reflector 1' will swin about its center of gravity into such aosition as is indicated by dotted lines, there throwing the lightwellt'o the rear as would be desirable In a deep window. The 0 enings sin the clamping ring 8 through which the various arms 9, g extend are ofsuch sizeas to permit the clamping ring to conform to the tilting'of thereflector 1' while being mov able into such relation tothe upper edge ofthe reflector and the arms as to lock the latter in engagement with thereflector.-

While the improved support for window reflectors has been shown inassociation with the improved shade holder and while many advantages'res'ult'from the adaptation of one to the other,it is to be understood,as is evident from the difierent embodiments illustrated, that one maybe used to advantage without the other. It will also be appreciwillsuggest themselves to skilled mechanics,

details of construction but all such departures involving expediencyonly are to be deemed within the scope of the invention provided thedesired results are obtained from devices which employ the principlesdescribed.
